Hey guys. My O2 sensor wire (purple) before the connector got too close to the exhaust manifold and it melted/burned the plastic conduit to it and fried about 2 inches of insulation off as well. However, the bare wire section did not ground to any metal or to the coolant gauge sender wire (green one). Knowing that my car has never run quite right once it warms up (rough idle, power loss), my questions are:

1.) Could this damage cause flaky O2 readings in closed-loop and possibly my driveability problems? Interestingly, after I installed Accel #23 injectors with about 43psi of fuel pressure, the car never leaned the mixture in closed-loop. No trouble codes.

2.) Can I fix it by simply splicing in another piece of 18 gauge wire using gold plated connectors and insulating it with thermo shield?

Thanks guys, I'm no electrician .

Should I do that or just re-insulate the exposed wire? Thanks.
